Dual - Fuel marine engines

Hi there,
what is dual fuel engine and its benefits.

 

Google is your friend here - I found this with Google. There are many other good links to be found as well.
Dual-fuel engines from Wärtsilä https://www.wartsila.com/encyclopedia/term/dual-fuel-engines-from-wartsila

 

Thank you, well the real question is how dual fuel engines produce NOx

 

?

 

NOx emissions from dual duel engines, how it works

 

The chemistry of burning doesn't change; the only difference is the engine accepts a gas or diesel.

 

Well the chemistry does change with fuel; Nox production is depending on peak flame temperature, which is influenced by fuel composition and properties. To some extent it may be controlled/reduced by inert gas, fi recirculated exhaust, in combination with varying pre-injection time.
